Abstract: ABSTRACT OF THE DISCLOSURE An ultrasonic transducer system for use with tissue is shown, which system includes a container of liquid acoustic coupling medium within which focused transducer means are located.  Focus-ing of the transducer means may be effected acoustically, as by use of an acoustic lens, and/or electronically, as by use of a transducer array.  The liquid medium container is closed at one end by a rigid acoustically transparent window, or diaphragm, for acoustically coupling to the skin and underlying tissue of the subject under investigation.  The material of the liquid acoustic coupling medium is selected so that the velocity of propagation of acoustic waves therein is substantially less than the velocity of the acoustic  waves within the tissue under investigation.  By using a low speed-of-sound coupling medium a shorter propagation path may be employed than is required by prior art transducer arrangements in which the speed-of-sound in the tissue and coupling fluid is substantially the same.  Operation in either scanning or non-scanning modes is contemplated, and scanning, when employed, may be effected mechanically or electronically.      In the sector scanning mode, the system may be operated in a manner such that the angular sector swept out by the focused beam in the tissue exceeds that in the low speed-of-sound liquid coupling medium as a result of refraction at the window interfaces.

Abstract: ABSTRACT DISPENSER CONTAINER     An improved container is both stackable and capable of forming a hopper to facilitate dispensing of articles therefrom.  To enable the container to withstand relative-ly large loads when it is placed in a stack, the container is formed with overfolded sidewall panels.  The top, bottom and end walls are single paneled for more economic fabri-cation.  A tear strip is formed across the top panel adjacent one end of the container to provide access to the interior of the container and to release a front end closure for outward pivoting movement about a fold line to form the hopper.

Abstract: TITLE OF THE INVENTION       FILAMENT-TYPE TRIMMER WITH AUTOMATIC FILAMENT FEED.     ABSTRACT OF THE DISCLOSURE     A filament-type trimmer comprises at least one filament spool carried by a rotary housing driven by a motor the speed of which increases with decrease in load.  Means for normally restraining rotation of the filament spool relative to the casing is responsive to centrifugal force to release the spool to feed additional filament when the speed of the motor increases due to decrease in load by reason of the extending end of the filament having become shorter by wearing or breaking off. In one embodiment. the feed of additional filament is delayed until by manual control the speed is reduced below normal operating speed.

Abstract: ABSTRACT           A method of and apparatus for measuring the flexural stiffness of a sheet like sample.  The sample is placed on an obliquely positioned surface with its upper edge above a hori-zontal clamping line.  The portion of the sample above the clamping line is of sufficient length so that when it is pivoted forward beyond the vertical the top portion of the sample is freely bent outward.  The free clamping length of the sample measured between the top edge and the clamping point is then reduced until the top portion of the sample independently pivots back onto the surface.  The residual clamping length thereby obtained is a measurement of the flexural stiffness.

Abstract: LOCKING DEVICE FOR RAISABLE VENETIAN BLIND     ABSTRACT         This invention relates to a locking device for a raisable or liftable ventian blind in which the bottom rail of the venetian blind includes an end piece extending into and guided by the side housing of the blind and in which a flexible lifting member engages the end piece of the bottom rail to raise and lower the same.  A spring urged pivoted latch is provided within the lower portion of the housing which automatically engages over the end piece of the bottom rail when it is in the lowered position and the tension in the lifting member is relaxed.  Thus the blind is locked in the down position.  When tension is applied to the lifting member to lift the blind, the lifting member moves the latch out of locking engagement with the end piece permitting the blind to be raised.

Abstract: RCA 69,530 A SUBWAVELENGTH MONOPULSE ANTENNA     Abstract of the Disclosure A sum channel waveguide is excited in a TE11 mode to cause a radio frequency wave to propagate therefrom through a cylindrical multimode waveguide.  The wave propagates via a discontinuity that causes the multimode waveguide to be excited in the TE11 mode and higher order modes.  The multimode waveguide is coupled to free space via a dielectric lens and a cup shaped matching section, whereby the wave causes a beam to be radiated from the lens.  The cavity of the multimode waveguide is contiguous with a plurality of arcuate cavities of a difference channel waveguide. The beam is deflected in response to excitation of the arcuate cavities.
